[0005] The distance between the plane and the upper surface of the bottom plate is the lower limit of the distance from the lower surface of the filter element upper end cover to the bottom of the filter element.

[0006] A plane 2 higher than the plane 1 is arranged on the outer side of the plane 1, and the outer edge of the upper end cover at the top of the filter element is smaller than the plane 2.

[0007] The distance between the second plane and the upper surface of the bottom plate is the upper limit of the total height of the filter element.

DETAILED DESCRIPTION

[0020] The utility model is further described below with reference to the accompanying drawings.

[0021] like Figure 1-Figure 6 As shown, the filter element 3 includes an upper end cover 3-1, a paper core 3-2, and a lower end cover 3-3 which are connected in sequence from top to bottom. One or more limiting plates 2 are provided above the bottom plate 1. A space for placing the filter element 3 is formed in the middle of the one or more limiting plates 2. A plane 2-1 is provided above the limiting plate 2. The outer edge of the upper end cover 3-1 at the top of the filter element 3 is larger than the plane 2-1. A pressure plate 4 is provided above the limiting plate 2.

[0022] The distance from plane 1 2 - 1 to the upper surface of the bottom plate 1 is the lower limit of the distance from the lower surface of the filter element upper end cover 3 - 1 to the bottom of the filter element 3 .

[0023] A second plane 2-2 higher than the first plane 2-1 is provided on the outer side of the first plane 2-1, and the outer edge of the upper end cover 3-1 at the top of the filter element 3 is smaller than the second plane 2-2.

[0024] The distance from the plane 2 - 2 to the upper surface of the bottom plate 1 is the upper limit of the total height of the filter element 3 .

[0025] The limiting plates 2 are fixed on the left and right sides and the rear side above the bottom plate 1 .

[0026] A cylinder bracket 5 is fixed above the limiting plate 2 , a cylinder 6 is mounted on the cylinder bracket 5 , and the lower end of the cylinder 6 is connected to the pressing plate 4 .

[0027] The cylinder 6 is controlled by a pressure regulating valve 7 and a manual valve 8.

[0028] An upper cover limiting block 2 - 3 is fixed above the limiting plate 2 .

[0029] When the utility model is used, the filter element 3 that has been injected with glue and assembled is immediately loaded into the tooling. During the loading process, the side surface of the upper end cover 3-1 will be limited by the upper cover limit block 2-3, and the side surface of the lower end cover 3-3 will be limited by the limit plate 2, ensuring that the upper and lower end covers will not be twisted or misaligned. When the filter element 3 is pushed to the bottom, it will be limited by the limit plate 2 on the rear side, thereby realizing the positioning function of the upper and lower covers.

[0030] When the filter element 3 is installed, the bottom of the upper end cover 3-1 is installed against the plane 2-1 on the left and right limit plates 2. If the height of the filter element 3 is lower than the lower limit, the upper end cover 3-1 will be close to the plane 2-1, and the paper core 3-2 and the lower end cover 3-3 will automatically drop under their own weight, thereby realizing the height raising function of the product.

[0031] During the installation of the filter element 3, if the top plane of the upper end cover 3-1 is higher than the second plane 2-2, it indicates that the height of the filter element 3 is greater than the upper limit of the size. Start the manual valve, drive the cylinder 6 to drive the pressure plate 4 to press down, the pressure plate 4 is pressed onto the second plane 2-2, and the top of the upper end cover 3-1 is pressed to be coplanar with the second plane 2-2, ensuring that the height of the filter element 3 does not exceed the upper limit, and realizing the height lowering function of the product. The pressure regulating valve 7 can control the pressure of the cylinder 6.

[0032] The filter element 3 is positioned in the tooling, pulled and pressed to the time required by the process, the manual valve 8 is unlocked, the cylinder 6 drives the pressing plate 4 to rise, the filter element 3 is taken out, and the filter element 3 is transferred to the next station.
